Re: 36" Coker tired DIY kit
Put a different 36" tire on and then it’s not a Coker. See what I mean? 
It’s a Coker, but it’s also a GB4. Both are essential parts of what your sweet new cycle is, but neither represent the whole thing. In the bike industry, bikes usually take their name from the brand on the frame. But unicycle frames are less of the total cost and structure of a unicycle, so I wouldn’t follow the same general rule.
I have a GB4 frame 29-er. It’s awesome. I can put a Big Apple tire on it and cruise with short cranks, or a mountain bike tire and 160 cranks and fly on the trails. The GB4 frame is a class act; light and stiff.
